Description
STONE & COLE. Expanding Tap. No. 16,151. Patented Dec. 2, 1856.
UNITED STATES PATNT OFFICE HARLEY STONE, OF UXBRIDGE, AND MASON D. COLE, OF BLACKSTONE, MASSACHUSETTS.
EXPANDING TAP.
Specification of Letters Patent No. 16,151, dated December 2, 1856.
To all whom it may concern:
Be it known that we, IIARLEY STONE, of Uxbridge, and MASON D. COLE, of Blackstone, both in the county of Vorcester and State of Massachusetts, have invented cer tain new and useful Improvements in EX- panding Taps or Reamers; and we do here by declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, in which drawings Figure l is a side view in perspective. Fig. 2 is a longitudinal section through its center. Fig. 3 is a transverse section through the line y. Fig. 4 is a transverse section through 0 p.
The same letters denote the same parts in all.
To construct our expanding tap the body or case A is made with a square part at B to turn it by, and with a cavity G from its end to D, and a smaller one E from I) to F and a hole through the remainder for the rod G to turn in, and also grooves the length of the cavity C or nearly so for the cutters S, S, S. The rod Gr has a square end to turn it by and a collar to keep it in place and a screw on the other end which reaches nearly to D and has a nut I fitted thereon. The nut I having studs or projecjections on its ends as seen in Fig. 4, which studs tit and play in spiral grooves cut in the cavity E, and the sides of the nut leaving room for the slotted part of the campiece J, which cam-piece is made with a number of volute surfaces corresponding-to the number of cutters, and fitting into cav: ity C, and a part fitting into cavity E which part is divided or slotted to pass the nut I and for that nut to slide in, at the end of the volute surfaces are collars attached to the cam-piece with curved slots corresponding to their surfaces. The cutters S, S, S, are made with lips at each end to it in the grooves in the collars of the cam piece and are fitted in the slots as grooves in A and have their outer surfaces threaded or toothed to cut the thread, the plate N covering the end of A and inclosing the other parts.
The operation is on turning the rod G one way it moves the nut I the ends of which following the spiral grooves turn it and thus turn the campiece by its slotted part and the cam surfaces force out the cutters S, S, S. And when the rod is turned the other way the nut takes the reverse direc tion carrying the campiece whose collars draw in the cutters by their lips. While to use the whole the force is applied to A by its square part or similar means; which opcrates the cutters without expanding them.
It will be seen that our invention applies to taps, reamers and mandrels equally well.
'lVe do not claim making expanding tools by means of cam surfaces irrespective of form and arrangement; but
o claim The arrangement of the campiece J the nut I and screw G, and their connection with the cutters and case A, when constructed and operating as above set forth and described.
In testimony whereof we have hereunto set our hands in the presence of two witneses.
